...which is easy enough to do. I've become quite familiar with the innards

OK, that's what I wanted to know. In which case:
: Besides, command line options suck for something you want every time.
I can just as easily leave the code inside make(1) as-is and override it in
<bsd.obj.mk>; the downside, of course, is that the default "find my objdir"
logic will get executed twice, causing more inode lookups and so forth.
And it won't fix the referenced PR.
To try this another way, how about a command line option that *turns off*
the built-in objdir logic? This could be used to address the PR.

In any case, I'll fiddle up an implementation of the <bsd.obj.mk> portion of
this proposal and post it to tech-toolchain for review as soon as it's done.
This will essentially duplicate some of the default .OBJDIR searching, but
with the mentioned benefits of more flexibility and less ugliness such as
that caused by the current implementation of BSDSRCDIR/BSDOBJDIR rewriting.
